World War One (WW1) Chin Strap for the M16 or M17 Helmet. This black leather strap has steel fittings, cotton stitching and is made in Germany. We have had these made up to provide WWI Helmet collectors with the best chin-strap possible for your M16 or M17 Helmet. These are AGED. The steel is rusty and the leather is dark, slightly shrunk and marked with age wrinkles in places. This strap is also suitable for the WW1 Stahlhelm, Pickelhaube and Shako such as the Jager (Jäger) or Gebirgstruppen (gebirgsjäger) Shako's.
